V claims.Vv (C1. 10s-'16) This invention relates to greenhouse construction generally and particularly to sash construction for greenhouses, and the primary object of the invention is to provide a new and improved 5 ventilator sash which is rigid in construction, which is efcient in operation, and which may be readily and economically manufactured and assembled, g

Other attendant objects of the invention are the provision of a novel greenhouse Ventilating sash which is-hingedly .connectedV to the greenhouse ridge bar in such a manner that the ridge bar cap provides a covering at` the upper en d y of the sash thereby preventing rain and snow from getting under the sash at its upper hinged end; the provision of a sash which will not warp and twist due to exposure to the elements, which is tight fitting and reinforced to make the sash easily operable by mechanical sash operatingv devices, which is provided with drip grooves in the longitudinal rails to catch condensation from the underside of the `glass panels, .and which is made up of smaller but stronger parts than conventional greenhouse sashesand therefore dispenses with shadows..

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

The accompanying drawing illustrates a selected embodiment of the invention and the views therein are as follows:

Fig. 1 is a detail sectional view of a greenhouse having the improved sash and ridge bar cap.

Fig. 2 is a detail sectional View of the sash showing its construction and the manner in which it is connected to the ridge bar.

Fig. 3 is a detail vtransverse sectional View on the line 3-3 of Fig. 2.

The greenhouse to which the sash is applied is preferably of Ythe type disclosed and claimed in applicants copending application, Serial No. 542,756, filed June 8, 1931. Thegreenhouse com- 45 prises a longitudinal ridge bar 5 to which a metal ridge cap 6 is attached. The cap 6 has a relatively fiat Upper side 7 from which side legs 8, 8 are bent downwardly at a predetermined angle. Rafters 9 have their upper ends connected to the 59 ridge bar'5 and support the glass roof panels 10.

The improved Ventilating sash, which is des- .4??? across the top or upper faces of the longitudinal cap thereby assuring positive operation.

sash bars while the angle leg 14 engages the upper endsof the sash bars 15.

The sash barsY 15 are preferably made'of wood and have outwardly extending shoulders 16, 16 which support glass sash panels 17. Grooves 18 .60 are provided in the bars 15 for the purpose of catching any water which may accumulate on the underside ofthe sash and drain this water to the outside of the greenhouse preventing it from dripping inside. 65

The sash 11 is positionedV relative to the ridge bar so that its upper end will extend beyond a leg 8, which leg provides a cover at the'upper end of the sash preventing rain and snow from getting in the space between the sash and the 'lo greehouse roof and falling inside of the greenhouse.

A hinge 19, having a relatively long leaf 20` and a relatively short leaf 21, pivoted together at 22,'is provided for hingedly or swingingly at- -5 taching the sash to the greenhouse. `The long leaf 20 of lthe hinge is fastened to'the sashin anyv convenient manner, such as by screws 23, while the short leaf 21 .is fastened to a leg '8 of the ridge' capby means of fasteners 24. Thus 80 the sash is hingedly connected to the metal ridge The over-hang of the ridge cap 6' covers the joint at the upper end of the .greenhouse at the'ridge bar. 1

The sash 11 has a lower or bottom rail 25 which is made of metal and is relatively narrow to assist in eliminating shadows. This rail 25 has an upper leg 26 upon which the glass sash panels 17 rest, and an inturned leg 27, which g3 rests upon a metal channel-shaped cross header 28, which cross head supports the bottom of the sash. Screws 29 hold the rail 25 to the bars 15 while fastening means 30 fasten the header 28 to the rafters 9. Glass clips 30 are engaged by 935 the glass roof panels 10, while end members 31, held by the screws 29, hold the glass sash panels 17 in place, there being zinc clips 32 positioned in the manner shown for the purpose of providing a resilient connection between the end L ;loo rails 25 and the glass 17.

Weep holes 33, spaced at intervals, may be provided in the bottom rail 25 as shown for permitting water draining along the bottom of the sash as well as Water carried by the drip grooves; 18 to pass throughthe rail 25 and discharge onto the main roof.

The ends of the bars 15 may have their ends cut away as indicated at 34 so that water. drained into the rail 25 may nd its way to thesweep holes 33 and then through the weep holes and onto the roof.

Other holes 35 may be provided in the header 28 to permit any condensation water finding its way into this header to drain out thereof and onto the main roof.

The invention provides a sash which is rigid, which will not warp, which reduces shadows in a greenhouse and which is positive in operation. The manner in which the sash is connected to the ridge cap provides for a covered connection preventing snow, ice, and water from getting in the joint. The sash can be economically manna factured and cannot be torn off in a wind storm like the conventional sash. Y Y
